DEVICE FOR FORMING- MULTICOLORED, BRAIDLIKE DECORATIONS.

Application filed March 24, 1928.

ments in a device of this chain to devices adapted to purposes and refers impor ant improvecter, which is disclosed in my co-pending application for Letters Patent of the U vember 15, 1927, Serial Although the device mentioned application nit-ed States, filed No- No. 233,454.

disclosed in the aforefor Letters Patent is well adapted to cause a twirling motion of a plastic substance and thereby also to cause the substance to be ejected from the device in a braid-like form, the different imitative strands of the e ected substance are all of the same color.

It is the main object of my present invention to construct a device of this character, not

only so that the plastic substance, when eject ed from the device, will be of a braid like form, but also so that,

if so desired, the different imitative strands of the ejected sub stance may differ in co e ected substance may b ing appearance than.

strands are of the same Another. object of the lor and that thus the e of a still more pleaswhen the different color.

present invention is not only to provide a device of this character with rotatable means f motion of the plastic or causing a ti irling substance and with ejecting means operable in conjunction with the rotatable means, but also to arrange fric tional means so that the latter may engage the rotatable means with any desired degree of tension in order to control the speed ot the rotatable means and thereby to cause the pitch of the imitative strands of the ejected sub stance to be uniform adapted to produce a eifect.

A further object and otherwise best required decorative of the invention is to prostance is ejected rotatable means, and to each nozzle so from the aforementioned construct and arrange that the exit opening of the nozzle may be positioned in proximity to the axis of the rotatable means for the plastic substance in order to prevent, as nearly as possible, a premature severance of the imitative strands of the substance during its ejection from the device.

Vith the above mentioned objects and with other objects in view, in the novel the invention consists construction and combination of parts hereinafter described, illustrated in the accompanying drawing s, and set forth inthe I is adapted to Serial No. 264,501.

appended claims,

the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing'from the spirit, or without sacrificing any of the advantages, of the invention.

In its preferred embodiment my present invention comprises a device, which in the drawings is designated in general by the numeral 10. This device includes a frame member 11, the major portion of which consists of a wide band 12, preferably made of spring metal and curved so as to form, when contracted, a virtually cylindrical wall. At the termination of each of its curved end portions, the band is medially provided with an outward extending lug 13, and these lugs have registering openings so that the lugs are adapted to receive therein a screw 14. The tendency of the band is to spring outward, and a nut 15, screwed on the screw 14, i press on one lug 18 while the head of the screw presses on the other lug so that the band may thus be contracted when so desired.

A substantially cylindrical body 16 is in the present instance shown as rotatably mounted in the ba. d 12 of the frame member stance that can .ing coaxial with the cylindrical and the plate 25 has preferably integral there-' 1 with a boss 27,

openin also co-axial with the body so as to erably of a square formation,

and as provided with endflanges 17, which overlap the band so as to prevent an excessive end play of the body within her. This body is provided with a plurality of cylindrical, tubular members 18, extending longitudinally in the body and somewhat beyond both ends thereof in parallelism with the axis of the body but concentrically thereo't'and being integrally joine, to the cylindrical wall oi. the body in any suitable inannerl Centrally oi the body 16 and preferably within one of the end flanges 17, is a web 19, to which the tubular members are also integrally joined. Owing; to this construction the tubular members may together be considered as a unit that is rotatable within the frame member, and the interior 'ot each tubular member maybe considered as a chamber, which is adaptcd to receive therein a plastic substance, such as sugar paste, plaster, papiei mache, or, in "fact, any plastic subbe twisted or otherwise shaped, while in its plastic state, so that braid-like decorat ns may be "termed thereof.

Each 01 the tuoular members 18 is preterably threaded at its ends, as shown at 20 and 21 in Fig. 4:, and in each of the chambers formed by the tubular members is reciprocatively mounted a suitable piston 22 so that the piston is adapted to discharge the substance from the chamber the discharge end thereof, which in. the present instance is shown to be at the end 20. Preferably, each piston is fitted on one end portion of a stem 23, which tends through a cap 241-, suitably perforated for the stem and screwed on the respective tubular member at the end 21. At its outer end each piston stem 23 has preterably therein a. threaded opening, and a plate 25 is suitably pertorated for receiving, therein screws 26, which are screwed into the stems and thereby secure the latter to the plate so thatthe stems and ti erewith also the pistons 22 may be-reciprocated in unison.

The web 19'has therein a threaded openbody 16,

which is provided with an "07 be adapted to receive rotatably therein the smooth portion 28 of a screw 29, the threaded portion oi the screw engaging the web 19. in its end beyond the portion 22 the screw 29 has a threaded opening, and the end is pretas shown at 30 in Fig. 2, while a crank 31, provided at one end with a handle 32, has therein at its other end a square opening that fits the portion '30, so that by means of a screw 33, screwed into the square end or the screw 29, the crank may be fixed to the latter. he screw 29 has preferably thereon between its threaded portion and its smooth portion a flange 3 1, which bears against the inner side of the plate 25 and thus co-operates with the crank, which the. frame mem exit opening; 36 of each nozzle stance, sugar paste of a selo I the nozzles are again screwe 1 ie spective tubular members to tl; 1r proper positions, as before described. The operator of the boss 27, for

bears against the outer end play of the preventing an excessive end screw relative to the plate.

llozzlestio are adapted to be used in conjunction with the tubular members 18. For this purpose each nozzle is threaded at its inlet end so to allow tl e nozzle to be screwed upon the respective tubular member the disel'iarge' end. 20 of the latter, and the N p is eccentric to the axis of the nozzles inlet end and to the axis of the respective tubular member to such a degree that, when the nozzles are screwed upon the tubular members, the exit openings 36 may be positioned in proximity to the axis 01 the cylindrical body 16, as shown in Figs. 1, 3, and 4;.

The frame n'ieinber l vided with a handle 2-37. device 10 is required, the o moves the nozzles from th v i bular members 18 and then grips the handle '7 with one hand. while with the other he 1 l'ccs hold the handle on the eranl: 3 and thereby turns the crank in the d'rcctio opposite to that indicated by the our ved arrow in 2, it being assumed that "the screw 29 has a right-hand thread thereon, so that the plate 25 s caused to be moved away 'tron'i the tubular members and that co cquently the pistons '22 are causedto be moved toward the ends 21 ot the respective br ar memers. Each tubular member with the required plastic sul thereafter adjusts the nut 15 upon th so 1 1- and thereby contract t frame member until it on body 15 with the desiiet and he again grips the dovi and turns the crank 31 in eater by the curved arrow in 2, ins causing a rotative movemento't the body 16 and therewith also a rotative movement or the tubular members 18 and sinni lieousiy causing the plate 25 to he moves toward the tubular memoers and thereby also ca" og the pistons to be moved toward the discgo ends 20 of the members so that the sugar paste isitorced "from the members into the nozzles and is eiccted from the latter through the e: a openings 36.

in the present instance the '6, but the imitative strands of the braid-like formation are colored according to the color of the substance inthe respective tubular members, so that one such imitative strand is red,'as shown at 39, one is white, as shown at 40, and one is-blue, as shown at 41 in the same figure.

The number of tubular members, of course, may be varied from two to any other number most adapted to cause the ejected substance to producea desired artistic effect. It should be further understood that, in accordance with the disclosure in my aforementioned copending application for Letters Patent, the exit openings 36 in the nozzles may be of any other shape than that shown in theappended drawings inorder to make it possible to pro duce a great number of pleasing variations in the appearance of the ejected substance 38 and thereby to increase the usefulness of the device 10. A peculiarly valuable feature of my invention is also that, by the adjustment of the tension of the frame member 11 upon the body 16, the latter may be rotated at different speeds, so that the pitch of the imitative strands of the ejected substance may thus be changed at the will of the operator of the device in order to produce further pleasing variations in the appearance of the ejected substance.

lVhile in the preferred embodiment of the invention, as shown in the drawings, the tubular members 18 are arranged within the cylindrical body 16 so as to form chambers for the pistons 22, the cylindrical body may in some instances be cast or otherwise suitably constructed, and it may have the piston chambers formed therein by boring or other means. In such a case the piston chambers may be internally threaded at their ends, and the caps 24 and the nozzles 85 may be correspondingly threaded Xternally so as to fit the ends of the piston chambers.

From the foregoing it is seen that the device '10, either in its preferred embodiment or otherwise constructed, as suggested, can

1 easily be operated by a single person and can be used in various arts for producing decorations of a braid-like appearance from a plastic substance, especially when it is desired that the imitative strands of the substance ejected from the device be of different colors.
